Beiersdorf & Co., A.G., Hamburg, Germany FiledSept. 14, 196i), Ser. No. 55,910 Claims priority, application GermanySept. 21, 1959 5 Ciaims. (Cl. Z22-L81) The object of this invention is asuspendable tube, the interior of which is intended for use with pasteor salvelike substance.

It has been proved useful to keep tubes intended for the care andprotection of the skin, and for similar purposes as closely as possibleto the place of their use. It is therefore advantageous to use tubesthat can be stored in a suspended manner.

There are already known tubes whose lower bent part-s are provided withsuspension means, thus enabling the tubes to be hung on a hook or thelike. Special means for suspension have to be provided, i.e., a hook, tosuspend the tubes in this determined manner.

The present invention dispenses with this disadvantage and enables theuser to suspend the tubes at any given place without the need of othermeans and without darnaging the place of suspension. According to theinvention, this is achieved by providing the closure of the tube with asuction device and with means for suspending such closure at theopposite end of the outlet opening.

There are also already known tubes provided with suction devices,intended to hold in combination with its closure the whole tube or itsdetached opening respectively. Thus the tubes can be stored either in anupward position with their `closed outlet openings directed downwardly,or in a suspended manner, with their closed outlet openings directedupwardly. No means have heretofore been provided to suspend tubes in anopen condition with outlet opening downward, by means of a suctiondevice.

According to the present invention, a detached tube closure is providedwith a suction device and can be pressed against a smooth surface, thu-skeeping the closure attached due to the -suction effect of the suctiondevice, and the tube can be suspended with its opposite end on the tubeclosure, thus disposing the tube in a hanging position with its openingextremity downward.

In a preferred embodiment of the invention the inner wall of the tubecase is provided at the end opposite to its outlet opening with alooplike perforation thus providing for the engagement of a hookprovided at the tube closure. This perforation can be located at theclosing -strip of the tube case, for instance in a tube groove or elsealong the welding line of the tube wall. It is advisable to provide theperforation with a rivet, to be used as an eye -for the reception of ahook secured to the tube closure.

Various possibilities of a design of the tube closure exist. The tubecapsule can be provided interiorly with an elastic, unneLshaped,increasing edge attachment forming at its inner side a suction cup andprovided at its outer side with a suspension hook. It is likewisepossible to place a suction device in inverted position over the tubecapsule consisting of an elastic synthetic material bulging inwardlyover the capsule and being outwardly likewise provided with a suspensionhook. In al-l instances the suction device, rather the rim, has to beproportionally adjusted to the tube shoulder so that the rim wiil bermly connected with the tube shoulder when the tube is closed and thusprotect it against damage.

3,078,017 retreated Feb. 1s, Vnass Y 2 Y The tube according to theinvention has the advantage that the tube, being lled for example with aprotective skin salve, can be "suspended inthe immediate vicinity of awater faucet. When utilizing synthetic tubes,the tube contents can beeasily extracted from the tube while the latter is in a suspendedposition, without being taken off the hook or without the necessity ofclosing its opening outlet after usage.

A preferred embodiment of the invention is illustrated in theaccompanying drawing, wherein FIG. 1 is a side view, in elevation, ofthe device;

FIG. 2 is a front elevation of the device;

FIG- 3 is a View of another embodiment;

FiG. 4 is an enlarged section of the device.

The device accord-ing to the invention will now be more fully describedwith reference to the accompanying drawing, but it should be understoodthat this is given by way of illustration and not of limitation and thatmany changes may be made in the details without departing from thespirit of the invention.

FIG. 1 shows a tube l with a tube -groove (notch) 2, which in the caseof synthetic tubes can be replaced by a longitudinal wel-d of the tubewalls and perforated at 3. The tube closure consists of a cap 5 made ofsynthetic material provided with a soft cap 6 of resilient syntheticmaterial. Cap 6 has a funnel-like elongation 7 abutting against tubeshoulder 9. At its opposite end the cap is provided with a hook-likeextension 8, adapted to -ft into perforation 3.

FIG. 2 is a side View of the -tube as shown in FIG. 1 with the tube capdetached and serving as a suspension means for tube 1.

FlG. 3 shows the perforation 3 by using a rivet 4 below the seam weld.This is especially of advantage when using synthetic tubes in order notto overtake or reinforce the welding seam.

FIG. 4 is a cross-section of a tube weld end with a hollow-type rivet.

We claim as our invention:

l. A suspendable tube for salve-like substances, comprising, incombination, a cylindrical container body, having an open neck portionand a closed flat end seam having an aperture therethrough, a detachableclosure for said open neck portion, said closure including a resilientconical cap adapted to be secured to a ilat surface by suction, and asuspension hook element integral with said closure, adapted to bereceived in said aperture for suspending the tube.

2. The tube according to claim l, further provided with a hollow rivetextending Ithrough said aperture toV reinforce the latter.

3. A suspendable tube for -salve-like substances, comprising, incombination, a cylindrical container body, having an open neck portionand a closed at end seam, a reinforced section formed with an aperturetherethrough, adjacent said flat end seam, a detachable closure for saidopen neck portion, said closure including a resilient conical capadapted to be secured to a flat surface by suction, and a suspensionhook element integral with said closure, adapted to be received in saidaperture for suspending the tube.

4. The tube according to claim l, wherein said neck portion is formedwith a truste-conical shoulder, extending from said neck portion to saidcylindrical container body, said resilient conical cap having theconfiguration of said frusto-conical portion.

5. A suspendable tube for salve-like substances, comprising, incombination, a cylindrical container body having an open neck portionand a closed fiat end seam, said seam having an aperture therethrough,said neck portion including a non-resilient mouth part, a detachablenon-resilient closure adapted to t over said mouth part, a resilientfrusto-conical cap integral with said closure, said cap being adapted tobe held by suction against a dat surface when said closure is detachedfrom said neck portion, and a hook elemen.` extending from said closure,adapted to be receivedin said aperture for suspending said tube.
